Dublin City Council manager Owen Keegan is to face a grilling today as D-Day on the Garth Brooks gigs approaches.

As Alan Kelly lay down a 48-hour deadline to rescue the five shows, the Dail's transport committee has agreed to haul in stakeholders to address the saga.

Mr Keegan, chief executive of DCC, will face questions on why he made the decision to block the shows and how he intends to fix it.

​​​Chairman of the Committee John O’Mahony TD said: “Last week, the Oireachtas Joint Committee on Transport and Communications agreed to request the attendance of key parties involved in the staging of the Garth Brooks concerts.

“The Committee agreed to invite the representatives of Dublin City Council, Aiken Promotions and the GAA to attend.

“The Committee notes the ongoing efforts in reinstating the concerts and remains hopeful that a satisfactory resolution can be found.

“The Committee shadows the Department of Transport, Tourism and Sport and is gravely concerned at the damage to Ireland’s reputation caused by the cancellation of the concerts, particularly given the upward trend in tourism numbers in recent years.

“The purpose of both meetings is to hear from each key player on the chain of events that have led to the cancellation of the planned Garth Brooks concerts.”
